1. Handheld electric beater-mixer adapted to drive selectively at least one so-called beating accessory such as for example a whip, or a so-called mixing accessory turning at high speed (38) such as for example a mixer foot, comprising a body (2) containing an electric drive motor (7), a rotatable c
1. Handheld electric beater-mixer adapted to drive selectively at least one so-called beating accessory such as for example a whip, or a so-called mixing accessory turning at high speed (38) such as for example a mixer foot, comprising a body (2) containing an electric drive motor (7), a rotatable coupling device (26) connected to the shaft (8) of the motor (7) and adapted for the securement and driving of the mixing accessory (38), said coupling device (26) communicating with the outside of the body through a coupling opening (32) provided in the body (2) and adapted for the engagement of the mixing accessory (38), and a closure (35) associated with said coupling opening (32), characterized in that the closure (35) is formed by at least two flaps (46) movable between a closure position in which they are together in the absence of the mixing accessory, and an open position in which they are spaced apart from each other toward the interior of the body (2), under the direct action of the mixing accessory (38) during the engagement of this latter in the coupling opening (32), said flaps (46) automatically returning to the closure position after withdrawal of the mixing accessory (38). 2. Beater-mixer according to claim 1, characterized in that the two flaps (46) are pivotally mounted in the body (2) respectively about two parallel axles (48, 49) located on opposite sides of the axis (XX') of rotation of the coupling device (26) and extending together in a plane transverse to the plane passing through said axis (XX') of rotation, the two flaps (46) being urged together by resilient return means (54) which tend to return them to the closure position after withdrawal of the mixing accessory (38). 3. Beater-mixer according to claim 2, characterized in that the resilient return means are constituted by two traction springs (54) which are interposed each between two shoulders (56, 57; 58, 59) formed laterally on the two flaps (46), and which extend on opposite sides of the two flaps in a same direction transverse to the pivotal axis (48; 49) of each of the two flaps (46). 4. Beater-mixer according to claim 2, in which the coupling opening (32) is of circular shape, characterized in that the two flaps (46) are identical and have a rectangular shape of which one of the large sides (51; 52) carries the corresponding pivotal axle (48; 49), and whose two other large sides are conjugated (61, 62), in the closure position of the two flaps (46), and extend facing and at a slight distance to each other, the two flaps (46) in the closure position defining together a rectangle in which is inscribed the circular coupling opening (32). 5. Beater-mixer according to claim 1, in which the mixing accessory (38) comprises a drive shaft (41) whose end is adapted to be coupled with the coupling device (26), characterized in that, after insertion of the mixing accessory (38) in the coupling device (26), the two flaps (46) in the open position bear with their free edges (61; 62) against the shaft (41) of the mixing accessory (38).
